Not one, and I'm pissed off, I really want to witness Chinese Aviation, such growth and diversity in Airlines. I want to go Beijing, amazing airport, busy scene, just love the top thee major airports in China, however I've heard a lot of bad things about the airlines.

LAXspotter - I've flown over 100 times with mainland China airlines. Never experienced any problems other than a few delays mostly related to weather issues. I'll be back in China in a week and have 4 more flights scheduled with CZ.

NG1Fan - 30K at a top speed of 431K/hour = 7 minutes. It is quite a ride.
